中文摘要 | 本篇論文針對去區塊效應濾波器來提出一種雙重濾波器的設計,此設計可以支援H.264多重視點視訊編碼(Multiview Video Coding;MVC)標準中的3D立體高階檔次(Stereo High Profile)。本設計使用暫存器陣列來取代內部SRAM,並提出一種資料交換的機制來處理巨圖塊動態幀場變換(MBAFF)格式,實施結果顯示處理每個MBAFF格式的巨圖塊時平均花費147個時脈週期,在0.13微米製程下的最高工作時脈達到250MHz,總共使用55.2K個邏輯閘並且不需內部SRAM,吞吐量效能最高達到每秒處理1,700,680個巨圖塊,可滿足每秒120張的高解析度(1920x1080)多重視點視訊相關應用。 |
英文摘要 | In this paper, a double-filter design of deblocking filter is proposed to support Stereo High Profile of H.264 Multiview Video Coding (MVC) extension. Without using SRAM for local memory, the proposed design adopts register arrays with a novel data exchange mechanism to efficiently reuse the intermediate data while filtering picture coded in macroblock adaptive frame field (MBAFF) format. Cooperated with the proposed parallel filtering orders for double-filter design, the proposed filter takes 147 cycles per macroblock in average. It is synthesized under 0.13m CMOS technology and it can be operated at 250 MHz. At the cost of 55.2K gates with 0 byte SRAM, the proposed design achieves the throughput of 1,700,680 macroblock/sec. Thus, it meets the requirement of 1920x1080 at 120 fps for multiview video applications. |
